"Showed up late, didn't install the bathroom fan as the manufacturer recommended (pic, fan5), dented the fan grille (pic, fan1). It was installed without the supplied support rails because he claimed he couldn't get in the attic. Now sure how I got the photos, then... The vent hose was kinked in the attic and hardly any air came out of the soffit, so I had to go into the attic to correct it. That's when I took the photos. Didn't give a price up front because apparently a bath fan with bluetooth speakers isn't in whatever book they price from. Not in the book? Overcharge. Generally very unhappy with the whole experience and will be looking elsewhere in the future. Not sure how when the customer supplies EVERYTHING but a romex clamp someone can charge so much. Absolutely unacceptable. $465 to have someone dent my fan, install it incorrectly, and throw out the parts that weren't used. Like the battery to the manufacturer supplied remote and the joist supports. I'm leaving the cost of service as originally quoted because it was only lowered to $465 after I complained about being ripped off."

"I hired Best Air Quality and Restoration to clean my dryer vent. I was very pleased with their level of professionalism. All my questions were answered without hesitation. The price was fair and affordable. Dennis, the technician notified me of his expected arrival time. He was very nice and pleasant. Dennis explained what the job entailed and completed the job within an hour. There was no excess lint or debris in my home to clean. I would recommend Best Air Quality and Restoration to others to experience for themselves. I intend to use other Best Air Quality and Restoration services again in the near future."

"Pohlman responded quickly when my water heater leaked and quickly replaced it at a competitive rate. I asked for multiple quotes and they were one of the first to respond. I appreciate the work, although I would have preferred to know which water heater was being installed before they put it in."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"The sales rep was very attentive when coming over and designing a solution to our heat and air needs. We were able to get a large team of workers here and knocked out an entire house install in one day. Some trash and miscellaneous items were left in our yard. When we needed additional items from the sales rep he will respond back saying he will take care of it but still has not. I have brought this up to him over 4 times and I still get nothing. The price seemed pretty high, and we had to shop the price around some but the company came with good financing options and some guarantees that others could not. The mini-split units work great."

Air Conditioning FAQs, answered by experts

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
